The cement manufacturing process starts from the mining of limestone, which is the main raw material for making cement. Limestone is excavated from open cast mines after drilling and blasting and loaded on to dumpers which transport the material and unload into hoppers of the limestone crushers.
In cement production, the mill is a key equipment, the ability to work the mill determines the efficiency of subsequent operations. In order to ensure normal production and the entire cement production line, ball mill production capacity must be guaranteed. Material from the three below, the structure of a ball mill, a new technology to improve the analysis method of the production capacity of the mill.
1.Material aspects: Friable material into the mill large, easy grinding, production capacity is high; production capacity is low and vice versa. Large size material into the mill, the mill must be loaded into the first position in a large ball more, so grinding can achieve the purpose of crushed material, the first position to a certain extent, they play the role of the crusher, causing grinding process is unreasonable, because the mill crushing efficiency is much lower than the crusher. So into the mill to reduce the particle size can increase mill production capacity, reduce power consumption. Feeding evenly, and feeding quantity is right, then the mill production capacity.
2.Aspects of the structure of the cement mill: The aspect ratio of the mill and production methods related to the mill open flow production system in order to ensure the fineness of a qualified product, an aspect ratio of 3.5 to 6, for the mill circle flow production system, in order to increase the material liquidity, should select an aspect ratio of 2.5 to 3.5. In the form of positions across the board mill, grate hole diaphragm plate number and size to be appropriate. Impact on the shape of the surface mill liner mill output is not small, because it can change the lift height grinding, that affect the impact grinding and grinding efficiency materials. Therefore, we should choose the right form of liner. The type of material in the mill grinding and grinding efficiency, size, grading and filling factor related. Therefore, we must correct and reasonable choice.
3.Adoption of new technologies: New technologies such as grinding system can be automatically controlled to enhance the mill ventilation mill water, add the grinding aids, these new technologies can improve the mill's production capacity.
